TiVO mini has no wireless built in as it is not the ideal connection type. You can use MOCA through your Coax connection or a LAN cable via a wireless Bridge, this is not ideal but it does work. Your main TiVO dies need to be connected via MOCA or ethernet as well in order ro work. You can't have your main TiVO connected via wifi and have the mini work.. if the TiVO is not connected via a wired LAN cable, or MOCA it will not work with the mini. This is by design. I use MOCA and my setup works perfectly, so if that is an option for you it may be the best solution.
